Cosmetics
Oral Contraceptives

Characteristics

2. Mild scale may be present
Distribution
1. Perioral region (most common)
  1. Narrow band of sparing immediately around the region of the lips
2. Perinasal region (common)
3. Periorbital Dermatitis (common)
  1. See Periocular Dermatitis (Periorbital Dermatitis) as below
4. Forehead
5. Cheeks
6. Chin
7. Neck

Eczematous Dermatitis
1. Mild Eczema may accompany the Perioral Dermatitis
2. However, typical Perioral Dermatitis is not Eczematous
Granulomatous Periorificial Dermatitis (known as Afro-Caribbean Childhood Eruption in black children)
1. Variant in pre-pubescent children
2. Small flesh or brown colored Papules (but no Pustules) in same distribution as typical Perioral Dermatitis
Periocular Dermatitis (Periorbital Dermatitis)
1. Scaly, Red Papules and Pustules around the eye and Eyelid
2. May be associated with Perioral Dermatitis or be isolated to the periocular region
3. Consider differential diagnosis
  1. See Eyelid Dermatitis
  2. See Eyelid Edema
  3. See Contact Dermatitis of the Eyelid

Eliminate topical irritants and allergans
1. Stop Topical Corticosteroids
  1. Expect an initial Perioral Dermatitis flare
  2. May taper off the Corticosteroid, or briefly step down to Hydrocortisone 1% before stopping
2. Limit topical agents on the face
  1. Use only hypoallergenic non-soaps on the face (e.g. Cetaphil Skin Cleanser)
3. Stop topical agents on the face (cosmetics, Skin Lubricants and other occlusive agents)
  1. May sparingly use hypoallergenic (non-perfume, no dye), non-occlusive Skin Lubricants
4. Once resolved or controlled, may slowly re-introduce hypoallergenic topical agents
  1. Re-introduce one product per week
Topical Agents
1. Topical Erythromycin 2% gel applied twice weekly
2. Topical Metronidazole 0.75% gel, lotion or cream once to twice daily
3. Topical Pimecrolimus 1% cream applied twice daily
  1. See Calcineurin Inhibitor regarding potential malignancy risk
Systemic Agents (for moderate to severe, refractory Perioral Dermatitis)
1. Tetracyclines
  1. Tetracycline 250 to 500 mg orally twice daily
  2. Doxycyline 50 to 100 mg orally twice daily (or 100 mg once daily)
2. Erythromycin (children <8 years old and pregnant women)
  1. Adults: Erythromycin Base 333 mg three times daily or 500 mg orally twice daily
Other measures: Acneiform Facial Eruption
1. Consider differential diagnosis
2. Consider treating as Acne Vulgaris with Comedolytics
